Off course, unfortunately bitcoin is going down on Christmas Day. Letter bit, i am not surprised, because i know that, it is not a even of bitcoin. Because it is not a Halving day. Suddenly bitcoin down in this day, than i guess people are using their bitcoin to celebrate the Christmas, may be the reason to going down the price of bitcoin. Otherwise i think within 2 days bitcoin would be grow up. So let see what is happening in the last week of the year.
